Who can undergo TMVR?

TMVR stands for Transcatheter Mitral Valve Replacement. It is a minimally invasive procedure used to replace a malfunctioning or diseased mitral valve in the heart. The mitral valve is responsible for regulating blood flow between the left atrium and the left ventricle.

In a TMVR procedure, a catheter is inserted through a small incision in the patient's leg or chest and guided to the heart. A prosthetic valve, typically made of biocompatible materials, is then deployed within the native mitral valve. This new valve takes over the function of regulating blood flow.

TMVR is often performed on patients who are considered high-risk or ineligible for traditional open-heart surgery due to various reasons, such as advanced age, significant comorbidities, or previous heart surgeries. By avoiding open-heart surgery, TMVR offers a less invasive option for valve replacement, which can lead to shorter hospital stays, reduced recovery times, and potentially fewer complications. Who can undergo TMVR?

The eligibility criteria for undergoing Transcatheter Mitral Valve Replacement (TMVR) can vary depending on several factors, including the specific patient's condition, the severity of the mitral valve disease, and the expertise and resources available at the healthcare facility. Generally, TMVR is considered for individuals who meet the following criteria:

1. Failed Surgical bioprosthetic Mitral valve who are high risk for redo-surgery (valve-in-valve TMVR)

2. Failed surgical mitral valve repair with mitral ring (Valve-in-Ring TMVR)

3. Severe degenerative mitral valve disease with dense mitral annular calcification (Valve-in-MAC)

It's important to note that each case is evaluated on an individual basis, and the final decision regarding suitability for TMVR is made by the medical team in consultation with the patient.

What is the difference between Mitraclip & TMVR?

MitraClip and TMVR (Transcatheter Mitral Valve Replacement) are both minimally invasive procedures used to treat mitral valve disease, but they have some key differences:

1. Purpose and Approach:
   

   • MitraClip: MitraClip is a specific device used for a procedure called transcatheter mitral valve repair (TMVr). It is designed to treat mitral regurgitation, a condition where the mitral valve fails to close properly, causing blood to leak backward into the left atrium. MitraClip is deployed to grasp and clip together the leaflets of the mitral valve, reducing the amount of regurgitation.

   • TMVR: TMVR refers to the broader category of procedures that involve replacing the mitral valve entirely. It is used in cases where the valve is severely diseased or damaged and repair with MitraClip is not feasible. TMVR involves deploying a prosthetic valve inside the native mitral valve, taking over its function.

1. Valve Repair vs. Valve Replacement:
   

   • MitraClip: MitraClip is primarily used for mitral valve repair. It allows the existing valve to be partially repaired by clipping the leaflets together to reduce regurgitation. The procedure aims to improve the function of the patient's own mitral valve without completely replacing it.

   • TMVR: TMVR involves replacing the malfunctioning or diseased mitral valve with a prosthetic valve. It completely replaces the native valve and assumes its role in regulating blood flow. TMVR is used when the mitral valve is severely damaged or if repair is not possible with MitraClip or other repair techniques.

1. Eligibility and Patient Selection:
   

   • MitraClip: MitraClip is suitable for patients with mitral regurgitation who may not be ideal candidates for open-heart surgery. It is often considered for individuals with moderate to severe regurgitation and significant symptoms.

   • TMVR: TMVR is typically considered for patients with severe mitral valve disease, including both mitral regurgitation and mitral stenosis, who are at high surgical risk or ineligible for open-heart surgery. TMVR is an alternative to valve replacement surgery.

In summary, MitraClip is a specific device used for transcatheter mitral valve repair (TMVr), aimed at repairing the patient's own mitral valve. TMVR, on the other hand, involves replacing the native mitral valve entirely with a prosthetic valve. The choice between MitraClip and TMVR depends on the specific condition of the mitral valve and the patient's individual circumstances.

Life after TAVI / TMVR

Life after Transcatheter Aortic Valve Implantation (TAVI) can vary from person to person, but in general, TAVI is designed to improve the quality of life for individuals with aortic valve stenosis.

Here are some aspects to consider:

1. Symptom Relief: One of the primary goals of TAVI is to relieve the symptoms associated with aortic valve stenosis, such as chest pain, shortness of breath, fatigue, and dizziness. After a successful TAVI procedure, nearly almost all patients experience an improvement in their symptoms and overall well-being.

2. Recovery Period: The recovery period after TAVI is typically shorter compared to traditional open-heart surgery. Most patients are able to resume their normal activities within a few days (<5-7 days), depending on their individual condition.

3. Follow-up Care: Regular follow-up appointments will be scheduled to monitor your progress after TAVI. These appointments may include imaging tests (such as echocardiograms) to evaluate the functioning of the implanted valve and check for any potential issues.

4. Medications, such as blood thinners or antiplatelet drugs, would be prescribed to prevent blood clots or manage other underlying conditions.

5. Long-Term Outlook: TAVI has shown positive outcomes in terms of improving quality of life and reducing symptoms. However, it's important to note that the longevity of the implanted valve can vary depending on factors such as the type of valve used and the patient's individual circumstances. Regular follow-up appointments and discussions with your healthcare provider will help assess the long-term outcomes and determine if any further interventions or monitoring are necessary.

6. Lifestyle Changes: While TAVI can greatly improve symptoms, it is essential to maintain a healthy lifestyle to optimize long-term outcomes. This may include regular exercise, a heart-healthy diet, weight management, and smoking cessation. Your healthcare team can provide guidance on specific lifestyle modifications tailored to your needs.

In general, Post-TAVI, patients can lead normal life.
